Constructor & Destructor Documentation

◆ TGLPolyMarker()

TGLPolyMarker::TGLPolyMarker ( const TBuffer3D buffer)

TAttMarker is not TObject descendant, so I need dynamic_cast.

Debug tracing.

Implements TGLLogicalShape.

Definition at line 55 of file TGLPolyMarker.cxx.

◆ DrawStars()

void TGLPolyMarker::DrawStars ( ) const

Draw stars.

Definition at line 125 of file TGLPolyMarker.cxx.

◆ IgnoreSizeForOfInterest()

Bool_t TGLPolyMarker::IgnoreSizeForOfInterest ( ) const
inlineoverridevirtual

Return true if size of this shape should be ignored when determining if the object should be drawn.

In this base-class we simply return state of static flag fgIgnoreSizeForCameraInterest.

Several sub-classes override this virtual function.

Reimplemented from TGLLogicalShape.
